To all whom it may concern:

Be it known that I, BENJAMIN SHINSAKU SUZUKI, a c1t1zen of the EmpireofJapan,

residing at Seattle, in the'county of Kingv and State of Washington,have invented new and useful Improvements in-Self-HeatingSoldering-Irons, of which the following is a specification.

The invention has relation to soldering irons or coppersgenerally usedby tinsmiths and has for its objectto provide a device of this characterwhich may be heated by vapor.

of liquid fuel with the result thatthe. device may be used continuouslywithout requiring the intermittent heating of the soldering iron orcopper as ordinarily constructed.

The invention inits specific adaptation is designed to utilize liquidfuel such as gasolene, which in the operation of the device is convertedinto vapor, such vapor being mixed with air and the resultant mixtureconsumed, and the heat resulting from combustion being utilized formaintaining the device at the required temperature.

The invention consists of a soldering device having a hollow head, aburner, a generator for converting the liquid fuel into.

vapor, a tank for holding a quantity of fuel, and means for regulatingth supply of such fuel to the burner.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated and claimed.

In the drawings hereto attached: Figure 1 is a side view of a solderingdevice embodying the invention. Fig. 2 is a central longitudinal sectionthereof. Fig. 3 is an enlarged sectional view of the head. Fig. 4 is anenlarged sectional view of the delivery end of the tank and thereceiving end of the generator showing the fuel regulating means.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawings by the samereference characters.

The solderingdevice comprises a hollow head 1, which is approximately ofpyramidal shape, the pointed end being used in the well known manner forapplying solder to seams, joints, and other work. An end piece 2 issecured to the base of the head 1, the said end piece having the shapeof a cross with the outer ends of its arms bent and riveted or otherwisesecured tothe sides of the head 1;. The end piece 2 is' formed at acentral point with aninternally threaded opening in which is fitted thethreaded end 3 of a tube 4 which constitutes the generator Openings 4.are formed in the sides of the tube 4 at orgnear the base .ofthethreaded, end 3. A nozzle-5 is arranged within the-tube 4 and issecuredthereto at a point beyond the openings 4, the outlet end ofthe nozzleextending acrossthe openings 4 within a short distance of the end ofthe, tube 4. The upper endof, thetube 4 .is enlarged and internallythreaded as indicatedat 6"and is adaptedto screw upon an externallythreaded nipple 7 at the lower j end of a tank 8. Aregulator is locatedin the upper portion of the tube 4 and consists of a thimble 9 and wick10, the upper end the enlarged portion 6 of the. tube so as to retainthe regulator in nlace.

The tank 8 has its lower end made tapering and is formed at its upperend withanl externally threaded collar 11, upon which a cap 12 isadapted to screw. A rod 13 is connected with the closed end of the cap12 and extends into the tank 8 and is provided at its inner or lower endwith a valve 14 which is adapted to close upon a seat 15 surrounding thenipple 7. By proper adjustment of the cap 12, the valve 14 may be movedmore orless so as to out off the sup ply of fuel to the burner or toregulate the supply according'to requirement.

In the operation of the device, fuel such as 'gasolene is supplied tothe tank 8 and uponopening the valve 14 a small quantity of fuel passesinto the head 1 after which the valve 14 is closed and the fuelcontained in the head is lighted, the flame serving to heat the head andthe tube 4, and when such parts are properly heated, the valve 14 isunseated to admit of the required quantity of gasolene or fuel passinginto the tube 4 which now acts as a generator and converts such fuelinto a vapor which escapes through the nozzle 5 and passes into the head1., Air is drawn into the lower end of the tube 4 through the openings 4and mixes with the vapor, the gaseous mixture being ignited at the endof the tube4 which constitutes a burner, thereby heating the head 1 andadmitting of the device being used. continuously.

. 75 of the thimble9 being enlarged to engage i the shoulder at theinner or lower end of v the deviceshown is merely illustrative and thatsuch changes may be made when desired as are within' the scope of theinven tion as claimed. 7

, Having thus described the invention, what is claimed as new is 1 1. Ina soldering device, the combination of a hollow head, a tube havingconnection with such head and constituting a generator and burner, aregulator arranged within such tube and consisting of a sleeve andabsorbent material carried by said sleeve, a tank having connection withthe tube, and a valve for regulating the discharge from the tank to thetube.

2. A soldering device comprising a hollow head, a metal end secured tothe base of the hollow head and provided with a threaded opening, a tubeadapted to make screw thread connection with the metal end and formed inits sides with openings, a nozzle arranged within the tube and extendingacross the openings in the sides thereof, a regulator arranged withinthe outer portion of the tube, a tank having connection with the tube,and a valve for regulating the discharge of the fuel from the tank intothe tube.

In testimony whereof I affix my signature in presence of two witnesses.
